>IF-MIB::ifDescr.1 = STRING: dc0

>but no luck
>I should add that if I run snmpwalk on this machine and use

>targetting the FreeBSD 5.3 machine from other machines I still
>get missing variables as above
>I have tried other combinations:
>- snmpwalk on FreeBSD5.3 machine accessing net-snmp 5.21 agent
>on Linux 2.6.8 kernel (Mandrake 10.1) - works OK.
>- Opposite way round to above. Doesn't work.
>- SNMP client on other platforms pointing to agent on FreeBSD
>5.3. Doesn't work
>- Net-snmp 5.09 built on FreeBSD 4.11 and 5.3. Doesn't work.
>So it seems to be reasonably independent of FreeBSD and
>net-snmp builds as far as I can tell.
>I'm not an expert on how net-snmp is glued into the kernel,

>certain calls are made. However, the strange thing is that the
>machine's mac addresses do seem to be present in other
>variables obtained from it - e.g. in some of the IP tables.
>I searched in the obvious net-snmp and FreeBSD places for
